Maybe it could move to "banned by default" for anything that is sold to the public, and authorized for very very narrow and particular applications that have little risk to contact the environment, although it's hard to study which application, maybe as long as the quantities produced are small enough that they're not a danger. For example, if it's for space satellite parts, or for nuclear energy application, etc, when alternatives don't exist as long as the quantity are small and as long as they're being disposed of safely. So in short: if it's a sector that is high value enough, where quantities are small and where safe disposal is mandatory.
